Perform as many supersets of pull-ups, sit-ups, and push-ups as possible in twenty minutes.

A superset is done by performing one set of each exercise back to back to back with little or no rest in between. Choose a number of reps that is well below your max to prevent early burnout during the training session. The training effect today will come from the overall volume of exercise combined with short rest periods, not max effort sets. Rest between supersets as necessary.

The sprints are progressive. The first sprint begins at a jog and climaxes at 50% of maximum effort; the second sprint goes from 40% at the beginning to 60% at the climax; the third sprint goes from 50-70%; the fourth sprint from 60-80%; the fifth sprint from 70-90%; the sixth sprint reaches 95% of maximum effort; the seventh and eighth sprints are run at 95-100% effort.

If you are not accustomed to the type of sprint training we do around here, do not max out on the final three sprints - climax between 80-90% of maximum effort.

If you are unable to recover sufficiently by jogging, reduce your pace to a walk. Go slower at first than you think is necessary. It is easy to overdo it on this workout. Vary your pace every one to three minutes throughout the twenty minutes training session.

If you are not accustomed to plyometric training or are obese, perform the Basic WOD.

Advanced:

12 Short Range Squat Jumps(Half-Squat Jumps: Squat until your elbows touch your knees and thighs are parallel to ground and then jump for height or distance)

12 Full Range Squat Jumps(Deep Squat Jumps: Squat deep until your hands touch the ground and then jump for height or distance)

20 High Tension Bodyweight Squats(Squat while maintaining conscious tension of the leg mucles)

Intermediate:

6 Short Range Squat Jumps

6 Full Range Squat Jumps

10 High Tension Bodyweight Squats

Basic:

5 Half-Squat Jumps

10 Lunges (Each leg)

10 Calf Raise and Flex

Are you tempted to cheat on the jump as your legs become tired? Try Traveling B-Circuits by jumping for distance instead of height. Try to cover the same total distance on each circuit as the workout progresses to ensure that you are pushing yourself adequately.

Complete five max sets of pull-ups at five minute intervals. Perform sets at 0, 5, 10, 15, and 20 minutes.

These are max sets but not to muscle failure. Perform the maximum number of repetitions possible while maintaining good form, but stop short of actual muscle failure (you may go to failure on the last set if you prefer).

Atlas Push-upsAtlas Push-ups: Place your hands in the seats of two chairs. With your body held straight, dip yourself between the chairs. This exercise is similar to a countertop push-up, but it stretches and utilizes more of the chest muscles.

Today's exercises can be found in many manuals on physical training. The above arrangement, however, was adapted from Pushing Yourself to Power by John E. Peterson. PYTP is a comprehensive collection of Dynamic Visualized Resistance and Dynamic Self Resistance exercises and includes many Isometric and Power Calisthenic exercises.

This is a challenging workout, but it is effective and very satisfying to complete. During the thirty seconds between sets of rope skipping you will complete a brief set of an additional exercise. Alternate sets of push-ups and sit-ups so that you perform ten sets of each during the twenty minutes.

You do not have long to perform each set. You also will need extra time to transition from skipping to pushing or crunching and back again. Plan to keep the sets small (e.g. 5-20 reps) and allow ~5 seconds for the first transition and 5-10 seconds for the transition back to the rope.

Start with sets of push-ups and sit-ups smaller than you think you can handle. This is a conditioning drill, not a strength workout.

This does not have to be done at an all-out sprint. Find a rhythm and work from one exercise to the other.
